Jeff says.......on page 243
The last term [K5/(Reliability+K4)] DOES NOT get used..... IF K5 = 0
So...if K5=0,
Metric = [K1*BW+(K2*BW/(256-LOAD)+K3*DLY]

As per Jeff Doyle the IGRP metric calc. formula is as
follows
[K1*BW+(K2*BW/(256-LOAD)+K3*DLY]*[K5/(Reliability+K4)]
By default K1=K3=1 and K2=K4=K5=0,
But if K5=K4=0 then the last term in the above formula
is zero (K5/Rel..), so then the product of any number
with a zero is zero, So how come the formula reduces
to
K1*BW+K2DLY
Can some one pls. explain....
Sandro
